Nope to almost all the 1st paragraph for the reasons i said in my previous post. Switch hardware sales are not "much more stronger, healthier" than 3DS. They are just better, just that, and i really think they are because Switch gmes in its first 2 years were better than 3DS ones, so that brought a lot more people despite Switch being more expensive.
Switch and 3DS were tied during first FY, Switch is going to have better sales in 2nd and 3rd. But that doesn't mean Switch is going to sell way better in the 3rd than the 2nd. People are trying too hard to convert Switch in DS and Wii, and Switch is not them. It will have a different pace during its lifetime, and my opinion, more similar to 3DS. Just my opinion of course.
And no to the second point too. Sorry Miyamotoo, you know we have already had this same discussion multiple times..... I still don't see this year having "much stronger lineup" than 2018. And even if it has better lineup this year, it doesn't need to translate to more hardware sales either. There are multiple examples in others consoles history where better software didn't translate to better sales (PS4 this year for example), but 3DS was the better one to compare because of how much they sold in 2014 compared to 2013, despite 2014 having better games (Monster Hunter 4, Pokemon X/Y, Luigi's Mansion 3D, Yokai Watch, Donkey Kong Country 3D, ....).
You missing point, they are stronger, but with fact they are better without price cut and revision that 3DS had in that time period, conclude they are much healthier/stronger:
-3DS FY 2012. - 13.5m vs Switch FY 2017. - 15m (note 3DS had huge price cut only 6 months after launch)
-3DS FY 2013. - 14m vs Switch FY 2018. - around 17m (note: 3DS had revision)
-3DS FY 2014. - 12.2m vs Switch FY 2019. - expected somewhere around 20m (with all thing counting, like very strong lineup, price cut and revision)
Talking about games, 3DS also had strong games in its first two full FYs.
I agree that Switch will have similar pace to 3DS in sales than to Wii (and buy that I think sales want fail of a cliff like in case of Wii and longer life span like 3DS), with diffrence that Switch will have quite stronger sales per years, and we already have situation where Switch will sell 3m units more in its 2nd full FY than 3DS did, and in 3rd year difference will be even bigger (easily 7m+, because 3DS had 12.2m year in FY 2014), not to mentioned 4. FY where 3DS sold 8.7m.
But its not point what you think about, but point is about things we do know: just currently confirmed 2019. games: NSMBU DX, Yoshi, Pokemon Gen 8, Animal Crossing, Fire Emblem, Luigi's Mansion 3, Daemon X Machina, Marvel Ultimate Alliance 3, Town...in same period of last year what we know about 2018. lineup was only Kirby, Mario Tennis, Donkey Kong TF and Hyrule Warriors DE, and thats with early January Direct while we still need to have 1st Direct this year where we will have new announcements in any case. Nintendo published games directly effect on sales, sales proves that, sales in 2018. until September were slower because they were not big new releases, sales explode with Mario Party, Pokemon Lets Go and Smash Bros. Comparing effects of releases on hardware sales of console thats in its 6. year on market and console that yets need to enter its 3. year on market dont make any sense, because buy that time consoles are near and of its life cycle and every console entered in lower sales years compared to previous years in any case.
